摘　　要：核电厂火灾情景下的人员可靠性分析(HRA)是核电厂火灾概率安全评价(PSA)中的重要内容。本文介绍了一种新的火灾HRA定量筛选分析方法 Scoping方法,并将其应用于某非能动核电厂火灾PSA建模中,将所得出的结果与运用NUREG/CR-6850筛选法得出的结果进行了比较。结果表明,Scoping方法一般具有更少的保守性,能合理地模化火灾情景下的人员失误,具有较好的工程应用价值。Fire HRA is one important element of fire PSA.This paper presented a new screening method of fire HRA which names‘scoping method’.The scoping method is more detailed than the method introduced in NURE/CR-6850 and it was applied to a fire PSA modeling of one passive nuclear power plant.The results were compared with those using the NUREG/CR-6850 screening method,and it was shown that the scoping method introduced in this paper is generally less conservative and is applicable for engineering projects.
